I think the 215,000 = Regina = Queen Victoria and the caravan = The British Isles = summer activities points to May 22, 2023. Princess Louise was born on March 18 and I think Rishi Sunak's Brexit vote (the store lottery counter) will take place on March 18, 2023. Maybe I find out what shaking hands means on May 22, 2023?
To Canadians, Victoria Day — the Monday before May 25 — on May 22 this year, signifies the beginning of summer and the arrival of warmer, greener days. Victoria Day is a Canadian holiday and is not observed in most of England. It is, however, celebrated in some parts of Scotland.
